The villa is being made of external insulation, and the internal layout is not already set, includin

According to the normal construction sequence, when doing external insulation, the main structure (including beams, plates, columns and walls, etc.) should have been constructed, and the basic layout of the house (including living room, bedroom, kitchen and bathroom, staircase, balcony, etc.) should have been finalized, and it is generally not suitable to make changes. However, for villa buildings, due to the high price and special customers, if there is a change in the requirements, the developer will require the design unit to change if possible according to the specific situation, but this change is very limited due to structural restrictions!

Yes, the insulation is done last.
